Thanks to fluid-filled gauges, any vibration from use is absorbed and deadened to ensure a precise reading. Along with precisely-manufactured components, the OTC Hydraulic Flow Meter, 50 GPM – 4277 measures flow accurately within 4 percent of full scale! It’s built to withstand immense operational pressure and is designed to provide you with sustainable readings over the long-term, even in the face of heavy, consistent use.

A testament to this product’s failure-resistant operation, an inner pass system features extra burst discs. This ensures that even in the event of overpressure conditions, the product won’t compromise in the form of fluid spills or lead to catastrophic damage to the unit itself. It supports bi-directional flow and can capably read flow in one direction.

Superior durability

The entire unit is housed within and protected by a durable steel case, ensuring its continued operation and resilience in the field. It’ll stand up to the rough-and-tumble conditions of industrial and agricultural situations.
